GLASS-DRAWING APPARATUS.

Tocll zc/Lom .t may concern: l

Be it known that I, WALTER A.. JoNEs, a citizen of the United States, residing at Columbus, in the county of Franklin, State of Ohio, have invented certain new and useful Improvements in Glass-Drawing Apparatus; and I do hereby declare the :following to be a full, clear, and eXact description of -the invention, such as will enable others skilled in the artl to which it appertains to make and use the same.

This invention relates to an improvement.v

. condition it has been found that it is a practical impossibility to draw the :next shell from the pot without first eliminating such vrefuse from the pot and from the walls thereof. In practice. it has been necessary to employ7 a ladle for removing all of such refuse. This operation necessarily requires 'a great amount of time and occasions a considerable loss to the manufacturer.

The principal object of the invention is to .provide a glass drawing apparatus of such a construction as to permit of the removal of that refuse within the pot as well as that which is adhered tothe walls thereof.

Another object. of the invention is to provide a glass drawing apparatus which includes a continuously supplied pot having a removablewall whereby upon the elevation thereof after the shell has been broken, the molten glass from the furnace will lreadily oyv over the bottom of the pot and thereby -carry off with it the'refuse contained within the pot and. also that which has become adhered tothe Walls of the mouththereof.

Another object` of the inventionis to provide a pot for the purpose describedwhich is provided with a removable Wall, the corres ondin abutting edges of the bottom and t e wa being of such construction as to j Specification of Letters Patent.

Application filed December 11, 191,1.: Serial No. 665,095.

' novel combination of forjthe glass from the tank, t

and in each opening there is disposed .a

. of and formed with an enlarged upwardly Patented eTama., 1913.-

readily permit not only the centeringofA the wall upon the bottom but of retaining thesame against accidental displacement.

lit-h these and other objectsin View, the invention consists in the `construction and j parts hereinafter fully described, illustrated in the accompanying drawings, `and pointed out in the claims .hereto appended; it being understood that various changes in the"form, proportion, 6"

size and minor details'of construction With- 'in the scope of the claims, may be resorted to without departing -from the spirit or sacrificing any of the advantages of the'invention. In the drawingsi Figure 1 is a vertical' se'ction of a glass drawing apparat-us constructed in accordance ivith my invention'. Fig. 2 is atop plan view of the pot and the furnace surrounding the same', the'cover bev-l :7 ing removed to better show the lnvention,

Fig. 3 is a bottom plan view of the bottom ofthe pot. j

' Like reference numerals designate corre-` spending drawings.

Referring tov the drawings, o designates `any suitable tank for containing molten glass. v ,-openmg` 6 m'wlnch is disposed a nose-block 8 Formed in' one wall thereof is an 7 having a conduit S which forms an outlet Disposed in. spaced relation to the tank and contiguous. to the nose-block 7 1s a furnace 9 having a bottom 10 and Walls .11'. 9

Formed inthe wall 11 adjacent the opening 6 of the tank 5 is alateral opening' 12. Also formed in the walls 11 above the bottom 10 is a plurality of spaced openings 13,

burner of any suitable type. Formed in the bottom 10 isa discharge opening l5 and integral with said bottom and projecting upwardly therefrom is a support 16. j j Disposed within the opening 12 of the furnace 9 is a pipe section 17, the outerend y 18 thereof, being connected to the nose-block 7 and the inner end projecting linto the furnace 9 in spaced relation to the walls there extending horizontal mouth 19. The bottomface 20 of the pipe section 17 is flat and the inner end of said section is seated upon the support 16. The mouth 19 projects above the plane of the pipe 17 to `form a circular parts in all the figures of the. 8

flange 21, the outer falce 22 thereof being out- Wardly-and ldownwardly inclined to form a seat.

My invention further comprises a re1nov' ableeircular j'wallV 23 having an undercut lower edge 24 corresponding to and adapted to fit upon the. seat ofthe mouth 19. .The n pper edgeof the wall 23 is formed with an outwardly extending peripheral flange 25.

Itwi1l.thus be observed that the wall 23 to fether with the mouth 19 conjointly form a glass receiving pot lt'roiny which shells may be drawn.. A bowl-shapedV cover 26 isseated upon the' walls 11 of the furnace 9,-and this .cover includesa metal band 28 havinga pluralityof eyes 429 secured thereto and adapted to`be engaged by hooks 30 carried by I. .hoisting chains 31 which in turnare con- .neted to a hoisting cable 32, said cable be# the. 'hooks-..29 of the hoisting cablel 32 are In ,practica the ing actuated by -any suitable means (not shown),

'able wall 23. The burners are employedforv 'the -purpose of keeping the molten glass within the A pot in a proper'condition to per- 'mit of a shell being drawn. When it is de- Sird'to 4'draw'a shell, the cover 2,6 is re- ,movedeby means of the hoisting cable S32-'and theshellis then drawn from the glass with.- inthe pot.v After the shell has been broken,

then'engaged with the peripheral flange -25 of the removable wall 23, and this wall is then elevated. As a result, the molten glass will flow fromthe furnace 5 over the flange 21'of the mouth 19 and carry olf all refuse glass with it.' Thisy molten glass together with the refuse passes down intothe furnace 9 and is thence directed therefrom through the outlet'- 15 to any suitable'place where it may-De reheated. The removable wall 23 is then lowered in vplace, and the operator is then ready to draw the next shell. It is to e observed that by means of this construc-l tion shells' may be successively drawn with- 'out any danger ofcreating flaws therein owing to the presence of refuse glass.

What is claimed: 1. The combination with a glass tank, of a housing adjacent thereto forming an independent heating chamber, avdrawing pot in said chamber and means for continuously supplying the pot with molten glass from the tank, said drawing pot including a removable wall portion. disposed entirely out of engagement with said housing and having its upper and lower edges positioned above and below the normal level of the glass in the tank whereby said wall portion may be` displaced independent of the displacement of any .portion of the housing to eect a draining of the glass at the extreme top of the drawing pot.

2,-The combinationv with a glass tank, of a housing 'forming an. independent heating chamber and having an opening inits top wall, a drawing pot in said heating chamber, means for continuously supplying the pot withmolten glass from the tank, said drawing pot including a removable wall portion projecting into the opening in the topsof. the honsingand having its outer face disposed in spaced relation to the wall of said opening and further having its upper and lower edges positioned above and below the normal level of the glass in the tank whereby said wall portion may be displaced .independent4 of. the displacement of thehousing'to effect a draining of the glass at the extreme top .of the drawing pot.

Intestimony whereof, I afliX my signature, in presence of two witnesses.
